A very good overview of geothermal exchange heating and cooling or ground source heat pumps
Reviewed in the United States on December 28, 2016
This is a very good book for someone wishing to better understand what geothermal exchange heating and cooling is and how it will greatly reduce the cost of heating and cooling a building. Written for the homeowner and incorporating the author's experience in going to geothermal, it is a pleasant read and is quite comprehensive. Not well understood and sometimes mistaken for geothermal electric power---which uses heat generated naturally deep within the earth for electricity generation---geothermal exchange heating and cooling (or use of ground source heat pumps) will significantly reduce the amount of energy used for heating and cooling for most temperate land areas. It is in much greater use in northern Europe, Canada, and elsewhere than in the U.S.A. Note: an excellent supplement to this book is the International Ground Source Heat Pump Association (IGSHPA) manual "Geothermal Exchange Heating and Cooling" which serves a comprehensive yet concise primer, primarily for the building owner seeking to reduce the heating and cooling energy costs for his/her building or the business person thinking of adding some aspect of geothermal exchange heating and cooling to his/her business line.
